v1.06 Changes & Enhancements:
  • Added a function in STL to access the 'Binary Result' that gets stored with the SAVE instruction. Use the keyword "BR" with either A, AN, O, ON, X and XN instructions to retrieve the saved result, e.g. "AN BR", for use in other Boolean operations.
  • Resolved a problem with 'Jump to Label' instructions where the node becomes unresponsive.
  • Changing a track transmitter's speed more than once in the same cycle caused endlessly repeated transmitter events.
  • Minor improvements to STL syntax error checking and messages.
